Copilot CLI update: chronicle, plugins, and fleet mode

GitHub Checkout

In this episode of GitHub Checkout, we sit down with Copilot CLI Product Manager Ryan Hecht to explore the latest experimental features. We cover the plugin marketplace, the /chronicle slash command for self-healing prompts, and how to run Claude Opus 4.6, GPT-5.4, and Gemini 3 simultaneously. We also walk through how /fleet mode and autopilot can handle massive refactoring tasks while you step away.

Datree

The Datree app allows engineering teams to automatically identify errors in newly committed YAML configs, including k8s manifests, and prevent these misconfigurations from reaching production.

On app installation, a new PR is created for each connected repository with a workflow for YAML (schema) validation. If one of the scanned (yaml) files happens to be a K8s manifest file, Datree will also run a K8s schema validation and a policy check for preventing K8s misconfigurations.
